Arsenal midfielder Chuks Aneke hit the winner for Crewe Alexandra in their League One victory over Sheffield United.
Aneke struck early in the second-half to see off the promotion-chasing Blades, who had already booked their place in next month's League One play-offs.
The mercurial 19-year-old picked the ball up on the edge of the box and fired a shot into the top corner for the only goal of the game.
